Persistence of produced water compounds in seawater determined by two biodegradation method
Biotransformation of natural gas and oil compounds associated with marine oil discharges
Biodegradation of produced water from a North Sea oil platform
Functional data analysis to study temperature dependent differences in biodegradation of oil
Biotransformation of potentially persistent alkylphenols in Natural seawater
Produced water (PW) discharged to the marine environment may contain both natural substances and industrial chemicals that are potentially persistent, bioaccumulating and toxic (PBT). Identification of substances as PBT is dependent upon accurate assessment of biodegradation rates, but these measure...
Surface weathering and dispersibility of MC252 crude oil
Results from a comprehensive oil weathering and dispersant effectiveness study of the MC252 crude oil have been used to predict changes in oil properties due to weathering on the sea surface and to estimate the effective “time window” for dispersant application under various sea conditions. MC252 oi...
Depletion and biodegradation of hydrocarbons in dispersions and emulsions of the Macondo 252 oil generated in an oil-on-seawater mesocosm flume basin
Physically and chemically (Corexit 9500) generated Macondo 252 oil dispersions, or emulsions (no Corexit), were prepared in an oil-on-seawater mesocosm flume basin at 30–32 °C, and studies of oil compound depletion performed for up to 15 days. The use of Corexit 9500 resulted in smaller median dropl...
Oil spill identification - OSINET - Round Robin 2012
The 7th Oil Spill Identification Round Robin within the Bonn Agreement Oil Spill Identification Network of Experts (OSINET) has been organized by Fugro ERT, Edinburgh. SINTEF received six oil samples (3 spill samples and 3 suspected sources) and has followed instructions (Ad_1) given by the organize...
Oil spill identification
The 6th Oil Spill Identification Round Robin within the Bonn Agreement Oil Spill Identification Network of Experts (OSINET) has been organized by CEDRE. SINTEF received 7 samples and has followed the instructions given by the organizers for analysis and data treatment. The GC/MS analysis showed that...
